BACKGROUND OF THE INVENTION

This present disclosure generally relates to the field of datacommunications.

More specifically, the present disclosure relates to facilitatingvarious types of communications, including secure, high-speed datacommunications, and voice communications when current end user devicesmay detect that little or no wireless or voice signal is available.Network failures and slow data communications occur for a myriad ofreasons—from crowded networks to natural disasters—leading tofrustrations in a society that is growing ever dependent on the abilityto transmit and receive communications, including secure, high-speeddata. Further, obtaining data and voice communication in remote areaswithout readily available power supplies, internet connectivity, and/orwhere cellular coverage is weak or non-existent can be difficult if notimpossible, which can be especially undesirable for public safetyofficials and others that often rely on data and voice communicationsfor work projects in rural environments and in disaster reliefsituations.

Conventional data communication units are large, bulky, and difficult totransport, and thus are typically retained in a generally fixed orpermanent location. Additionally, conventional, portable antennas aretypically located on the outside of a data communications unit, creatinga cumbersome device that is not aesthetically pleasing, where theantennas are freely exposed to external wear, tear and breakage.

What is needed then are improvements to data communication units.

An antenna array 31 can be in electrical communication with routerdevice 14. Antenna array 31 can include one or more cellular antennas32, one or more wireless network (e.g. Wi-Fi®) antennas 34, and at leastone global positioning system (GPS) antenna 36 secured, retained within,or attached to an inside surface 13 of case 12. In certain embodiments,antennas 32, 34, and 36 of antenna array 31 may be attached to lidinside surface 13 b of lid 44, as shown in FIGS. 1 and 6. In otherembodiments, as shown in FIG. 12, antenna array 31 can be secured in,retained within, or attached to base 42 of case 12. In some embodiments,each antenna 32, 34, and 36 of antenna array 31 can be separatelymounted or attached within case 12, as shown in FIG. 1. In otherembodiments, each of the antennas of antenna array 31 can be containedtogether in an antenna housing 64, and antenna housing 64 can becontained within or attached to either base 42 or lid 40 of case 12 at asingle location, as shown in FIG. 12. The location of antenna array 31inside case 12 is beneficial because conventional, portable antennas aretypically located on the outside of a data communications unit, creatinga cumbersome device that is unaesthetically pleasing where the antennasare freely exposed to external wear, tear and breakage. In contrast,antennas 32, 34, and 36, as well as the other electrical components ofapparatus 10 are protected by case 12 when lid 44 is in the closedposition, which can help prevent damage to the integral electricaland/or communication components of apparatus 10. When lid 44 is in theclosed position, case 12 can enclose and protect power supply 24, routerdevice 14, and antenna array 31, as shown in FIGS. 2 and 7.

In the embodiment shown in FIG. 1, two cellular antennas 32 are utilizedto cover frequencies across 700 and 800 MHz as well as all globalcellular frequencies from 698-960 MHz and 1710-2700 MHz. Cellularantennas 32 of the embodiment in FIG. 1 may require a ground plane. Forthe embodiment shown in FIG. 1 and discussed above, It has beendiscovered that vertical polarity cellular antennas requiring a groundplane may be particularly advantageous. Ground plane independentcellular antennas and horizontal polarity cellular antennas, however,may also be used in other embodiments. Cellular antennas 32 of theembodiment in FIG. 1 may allow for multiple user and multiple-input andmultiple-output (MiMo) applications. As shown in FIG. 9, cellularantennas 32 can be positioned at a cellular antenna separation distance54 from one another within case 12 to help reduce frequency interferencebetween cellular antennas 32. In one embodiment, cellular antennaseparation distance 54 is at least 12 inches.

In certain embodiments, GPS antenna 36, as shown in FIG. 1, can beincluded in the data communications case. In one embodiment, the GPSantenna has an operating frequency of 1575 MHz, but many other operatingfrequencies may be utilized. In one embodiment, GPS antenna 36 can havea low-noise amplifier gain of 26 decibels, and an impedance of 50 ohms.A plurality of GPS antennas may be used. The GPS antenna(s) may beactive or passive GPS antennas.

In certain embodiments, the wireless antennas 34, as shown in FIG. 1,have a frequency range of 2.4/5 GHz. In certain embodiments, thewireless antennas 34 enable multiple user and multiple-input andmultiple-output applications. In certain embodiments, a user may be ableto utilize a virtual private network (VPN) with any combination of themultiple wireless networks and/or any wired network port. In certainembodiments, more than two wireless antennas can be used to furtherincrease the capacity of the wireless network and to further supportMiMo applications.

Antenna cables 52 may connect various components inside the case 12 tothe antennas 32, 34, 36. The antenna cables 52 may be channeled througha conduit 51, which allows for discrete and organized bundling of theantenna cables 52 and other cables connecting components within thecase. Various components inside the case 12 may also be interconnectedwirelessly. It is advantageous to utilize cables having as short as alength as possible to avoid attenuation. It is also advantageous toutilize low attenuation cables.

In certain embodiments, as shown in FIGS. 1, 3, and 6, antennas 32, 34,36 are securely mounted within case 12 to lid inside surface 13 b of lid44. Apparatus 10 can include a plurality of mounting brackets 55 whichcan be adhered to lid inside surface 13 b. Each antenna 32, 34, and 36of antenna array 31 can be secured inside lid 44 to a correspondingmounting bracket 55. In some embodiments, each mounting bracket 55 canbe substantially L-shaped. A first bracket portion 55 a of bracket 55can be positionable substantially parallel to lid inside surface 13 b,first bracket portion 55 a being adhered to lid inside surface 13 b. Asecond bracket portion 55 b can extend away from lid inside surface 13 bwhen mounting bracket 55 is adhered to lid inside surface 13 b. Acorresponding antenna, shown as GPS antenna 36 (by way of example only)in FIG. 3, can be mounted to second bracket portion 55 b. In oneembodiment of the invention, second bracket portion 55 b may be shapedand sized to serve as a ground plane for any one or more than one of theantennas of the antenna array.

In certain embodiments, as shown in FIG. 3, each mounting bracket 55 caninclude at least one resilient polymer stud 56 having a stud length 59.Polymer studs 56 can be adhered to an inner surface 13 of case 12, andin some embodiments to lid inner surface 13 b, and to first bracketportion 55 a of a corresponding mounting bracket 55 such that mountingbrackets 55 are adhered to lid inner surface 13 b via polymer studs 56.Particularly, one end of each stud 56 can be adhered to lid innersurface 13 b, and an opposing end of each stud 56 can be attached oradhered to first portion 55 a of a corresponding mounting bracket 55. Insome embodiments, as shown in FIG. 3, each mounting bracket 55 can havean internal grommet or hole within the first portion 55 a of mountingbracket 55 and each polymer stud 56 can have a threaded receptacle suchthat first portion 55 a of mounting bracket 55 can be secured to polymerstud 56 by a screw, bolt, or other suitable fastener 57. In someembodiments, a washer 53 can be positioned between mounting bracket 55and fastener 57 to help disperse the force of fastener 57 againstmounting bracket 55.

In other embodiments, one end of each stud 56 can be adhered to lidinner surface 13 b, and an opposing end of each stud 56 can be adheredto first portion 55 a of a corresponding mounting bracket 55. In stillother embodiments, each polymer stud 56 and corresponding mountingbracket 55 can be integrally formed together as one continuous orunitary piece.

In certain embodiments, studs 56 can have a circular longitudinal crosssection including a diameter of at least 0.5 inches and a stud length ofat least 0.5 inches. In some embodiments, studs 56 can have a diameterof about 0.825 inches and a length of about 1.25 inches. Studs 56 cantherefore extend inward from lid inner surface 13 b a distance of atleast 0.5 inches. Studs 56 can be comprised of a resilient polymercapable of dampening shock and vibration, such as polychloroprene. Incertain embodiments, each stud 56 may be secured to lid inner surface 13b of lid 44 by a structural adhesive 61, such as a structuralcyanoacrylate. One example of a suitable structural cyanoacrylateadhesive is BP Blue™, which can be purchased from Tech-Bond Solutions™of Columbus, Ohio. In certain embodiments, the opposite ends of eachstud 56 can also be secured to corresponding mounting brackets 55 via asimilar structural adhesive, such as the structural cyanoacrylatediscussed herein. While other mechanisms may be used to secure theantennas within case 12, structurally adhering studs 56 to correspondinginner surface 13 of case 12 via structural adhesives such as structuralcyanoacrylates can allow antennas 32, 34, and 36 to be secured withincase 12 without having to penetrate case 12.

Referring again to FIGS. 1 and 3, mounting brackets 55 used to secureantennas 32, 34, and 36 within case 12 should be configured to allow forsecure placement of antennas 32, 34, and 36 on corresponding mountingbrackets 55 via suitable antenna fasteners (e.g., screws, nuts, bolts)and to provide any necessary ground plane for antennas 32, 34, and 36.Mounting brackets 55 and the fasteners used to hold antennas 32, 34, and36 in place on corresponding mounting brackets 55 within case 12 mayinclude powder coated steel or stainless steel.

Mounting brackets 55 can be positioned at a predetermined distance awayfrom the inside of case 12 via polymer studs 56, in some embodiments adistance of at least 0.5 inches, such that antennas are located at asufficient distance from lid inner surface 13 b of lid 44 so that case12 may be comfortably closed, and so that antenna array 31 may haveunimpeded, open-air exposure when lid 44 is in the open position.Affixing antennas 32, 34, and 36 to mounting brackets 55 on innersurface 13 of case 12 can allow for case 12 to be waterproof anddustproof and can help reduce the problem of antennas 32, 34, and 36being easily dislocated or knocked off a data communications unit.

As shown in FIGS. 1 and 8, Apparatus 10 can include a plurality offastening straps 26 adhered to case 12. Each of power supply 24, routerdevice 14, and power switch 22 can be secured within case 12 with atleast one corresponding fastening strap 26. Fastening straps 26 mayincorporate hook and loop fasteners, zippers, removable adhesives,buttons, snaps, clips, or any other suitable fastening members to securefastening straps 26 together around corresponding components ofapparatus 10 to secure the components within case 12. Fastening straps26 in some embodiments can include audible snap closures. Fasteningstraps 26 can be adhered or structurally bonded to either base 42 or lid44 as desired to secure the various components of apparatus 10 to eitherbase 42 or lid 44.

In some embodiments, fastening straps 26 may be sewn, adhered, orotherwise attached to corresponding polymer strips 60. Polymer strips 60can be adhered to inside surface 13 of case 12 by a polymer stripstructural adhesive 62 such as a structural cyanoacrylate. As such,fastening straps 26 can be adhered to case 12 via polymer strips 60. Apolymer strip structural adhesive 62 including a structuralcyanoacrylate can form a covalent bond between polymer strips 60 andinside surface 13 of case 12 to help provide a strong and reliableattachment of polymer strips 60 to case 12. Adhering polymer strips 60and fastening straps 26 to case 12 can help maintain the integrity ofcase 12 as polymer strips 60 and fastening straps 26 are not secured tocase 12 by mechanical fasteners such as screws or bolts that canpenetrate case 12.

In some embodiments, fastening straps 26 may be sewn to the polymerstrips 60 using sewing thread that meets or exceeds U.S. militaryspecifications. In other embodiments, fastening straps 26 can be adheredto polymer strips 60. In still other embodiments, the fastening straps26 may be adhered directly to inner surface 13 of case 12.

Polymer strips 60 may comprise polychloroprene, nylon-reinforcedpolychloroprene, or another suitable polymer. Polymer strips 60 made ofnylon-reinforced polychloroprene have been found to be particularlyadvantageous.

In some embodiments, as shown in FIG. 1, router device 14, power supply24, and power switch 22 can be secured in base 42 via suitable fasteningstrips 26, and each antenna 32, 34, and 36 of antenna array 31 can besecured within lid 44 via a corresponding mounting bracket 55.
